Rear drums

<< < (2/2)

Agent47:
I'd like to go back to the original size, the 230mm Passat onesare huge, way over powered, and weigh loads. I've got the Vauxhall caliper setup on the front so I don't need extra braking really. I've been looking and it seems that the mk2f backing plates are hard to find, but I can find new 6n ones. If 6n ones work I'll put them off a car I have and get everything else new. I'd just prefer to get new everything.

same as mk2...try the face book pages for mk 2/2f  will get some used ones on there

Agent47:
Trying to clear up a small headache. I took the entire drums off my 6n, got all new shoes, mounting kit and drums. The question now is, the brake cylinder. Should be aluminium and 17.5mm bore diameter, this is where im getting confused. The chassis I have has the regulator removed, so without getting a new one and everything that goes with it,  i want less pressure on the rears. From looking through way too many parts shops, there appears to be 3 choices, 15.5mm, 17.5mm (standard) or 19mm cylinder bore diameters.
This is where the internet gets contradictory, for the same force at the pedal, which would give me less pressure at the rear?

steveo3002:
smaller ones for non reg brakes
